Preparation method for disposable pants-type sanitary articles

Abstract

The invention relates to the field of sanitary articles, provides a preparation method for a disposable pants-type sanitary article, solves the problems in the prior art that the pants-type sanitary article has a complex preparation technology and a high cost, and also solves the problems that a tightening feeling is generated since the outer clothing layer of the disposable pants-type sanitary article obtained by the preparation method in the prior art is poor in flexibility and uneven in elastic distribution. The preparation method comprises the steps of: preparing an outer clothing layer, preparing an absorption body, fixedly arranging the absorption body on the outer clothing layer, welding the outer clothing layer to obtain a pants-type structure, and carrying out slitting to obtain asingle product. The step of preparing the outer clothing layer comprises the following steps of: a: preparing elastic nonwoven cloth; b: sending the elastic nonwoven cloth prepared in the step a intoan activation system to be subjected to activation processing; and c: after the elastic nonwoven cloth prepared in the step b is slit along a longitudinal direction, and compounding the slit elasticnonwoven cloth and spunbond nonwoven cloth into a whole through hot melt adhesives or ultrasonic waves, wherein each piece of slit elastic nonwoven cloth to be independently is positioned on two longitudinal sides of the spunbond nonwoven cloth, so as to obtain the outer clothing layer.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to a method for preparing disposable pants-type sanitary products. Background technique [0002] The preparation method of disposable pants-type hygiene products generally includes the preparation of the outer clothing layer and the preparation of the absorbent body. The outer clothing layer generally includes a front clothing layer and a rear clothing layer. One end of the absorbent body is fixedly connected to the front clothing layer, and the other end It is fixedly connected with the rear clothing layer, and the lateral sides of the front and rear clothing layers are fixedly welded to form a closed structure with a waist opening and leg openings. There are two common structures for the front and rear clothing layers, one is a one-piece structure, and the other is a two-piece structure. The clothing layers of these two structures are usually composed of two layers of non-woven co...
